Can you open up the modulator and trace the wiring?

That's plan B. Here goes...

... later.

Four wires terminating at a socket on the modulator PCB. Each pin is
labeled on the PCB, although the labels are partially obscured by the
socket. They appear to read (with corresponding wire colours):

A (Red)

G (Brown)

V (White)

B (Black)


Do you have a multi-meter?

If so, connect the cable to the camera
turn on camera and play a tape (or put it into camera mode!)

Now poke the connections inside the modulator and look for the 5v
It's probably on Red and Black
now measure the -ve from the 5v to the other two connections, one of them
will show about 1v (varying) this is your video signal - the last one is
audio :-)

My guess would be...

A (Red) - +5v

G (Brown) - Audio

V (White) - Video

B (Black) - Ground

But you won't know unless you poke it :-)

Sparks...
